Liebherr LTM 1055-1 Mobile Crane Technical Information and BMK Components Manual (Superstructure) (SN 055662)

The Liebherr LTM 1055-1 Mobile Crane spends its life lifting on tight sites where downtime kills your schedule and your budget. When something electrical or hydraulic misbehaves, the techs and electricians reach first for wiring diagrams, then immediately need a BMK / component identification guide to find the actual hardware. In most workshops I’ve seen, that’s the only way to turn a fault code or schematic tag into “this box, on this side of the upper.” That’s exactly the gap this Technical Information & BMK Components Manual for the superstructure is meant to fill.

What this manual helps you do

• Identify which physical component on the superstructure matches a schematic tag like K15, V12, or X45.
• Locate relays, valves, sensors, and junction boxes on the upper by using clear outline and layout diagrams.
• Trace reference designators from Liebherr wiring or hydraulic diagrams to their real-world mounting positions on the crane.
• Cross-reference component IDs with other Liebherr documents so your techs talk the same “language” as the fault codes and schematics.
• Pinpoint what a component is called in Liebherr’s nomenclature so you can then look it up correctly in the parts catalogue or service info.

Who this is for

This BMK component identification manual is aimed at workshop technicians, field service techs, electrical diagnostic engineers, fleet mechanics, and trainers. If you’re looking for repair steps, torque specs, or part numbers, you’ll be disappointed – you need a service manual or parts catalogue instead.

FAQ

Q: Is this a clear, searchable PDF with readable diagrams?

A: Yes, it’s a PDF that’s meant to be zoomed and searched so techs can quickly find component IDs and locations.

Q: Does it cover the carrier as well as the upper?

A: No, this BMK manual only covers the superstructure on SN 055662, not the lower carrier, chassis, wheels, or outriggers.

Q: Does it tie in with other Liebherr manuals?

A: Yes, the BMK for the Liebherr LTM 1055-1 Mobile Crane is designed to work alongside wiring diagrams, parts catalogues, and service manuals by sharing the same component IDs.

Bottom line: If your main need is to know “where is this component on the upper and what does Liebherr call it?”, this is the right document. If you want how-to repair info or ordering data, this is not what you’re after.
